Hi Everyone! For anyone who uses an iPad Mini 2 for general browsing, document editing and light stuff; is iOS9 still performing well on the A7 chip? I'm not sure what the 5S chip was, but I'm thinking of buying a refurb'd iPad 2 mini for my girlfriend to replace her well broken iPad 2 on iOS7. It's started crashing on web browsing regularly too. iPad mini 3 is totally out of the window as it's pretty much the same as the iPad 2.
